Aircraft anti-terrorism security system
First Claim
1. In an aircraft having a fuselage, a floor in said fuselage, a below-deck space in said fuselage below said floor, a cockpit in said fuselage above said floor, a cabin in said fuselage adjacent to said cockpit above said floor, a cockpit wall separating said cockpit from said cabin, and a cockpit door arranged in said cockpit wall to selectively open or close a passage through said cockpit wall between said cabin and said cockpit,an improvement comprising:
- an enclosed security cell arranged below said floor in said below-deck space at a location adjacent to and extending aft from said cockpit door, wherein said security cell is large enough and adapted to receive and confine a person therein;
a trap door arrangement including a trap door arranged in said floor in said cabin at a location adjacent to and extending aft from said cockpit door, and a power actuator connected to said trap door to actuate said trap door to selectively open or close a passage through said floor from said cabin into said security cell; and
at least one feature selected from the ground consisting of;
a first feature wherein said security cell is structurally strong to withstand a firearm discharge and a bomb explosion, and a second feature wherein said security cell is airtight, said trap door is hermetically sealed when closed, and said improvement further comprises a knock-out gas source providing a knock-out gas, and a gas nozzle connected to said knock-out gas source and arranged in said security cell to introduce said knock-out gas into said security cell.

Abstract
In an aircraft cabin floor adjacent to the cockpit, a trap door opens downwardly into a security cell, to trap a terrorist trying to enter the cockpit. Two walls with lockable airtight doors bound a safety buffer cabin between the cockpit and the passenger cabin. Sensors like seat occupancy sensors, motion detectors, video cameras and microphones provide data regarding the location, movement and activities of passengers to a system that evaluates the data to recognize unusual data situations indicating one or more escalation levels of suspicious or aggressive actions by passengers. Alarm signals and terrorist countermeasure devices such as fogging or tranquilizer gas generators, noise generators, high intensity blinding/glaring lights, a cabin lighting master shut-off, window darkening devices, and tranquilizer dart guns are actuated automatically by the evaluation system, or manually by a cockpit input device or a portable signaling device carried by a flight attendant.

4. In an aircraft having a fuselage, a cockpit in said fuselage, a cabin in said fuselage adjacent to said cockpit, a cockpit wall separating said cockpit from said cabin, and a cockpit door arranged in said cockpit wall to selectively open or close a passage through said cockpit wall between said cabin and said cockpit,
an improvement comprising: -
a security wall arranged spaced apart from and parallel to said cockpit wall in said cabin so as to separate said cabin into a safety buffer zone cabin between said cockpit wall and said security wall, and a passenger seating cabin on a side of said security wall opposite said safety buffer zone cabin;
a security door arranged in said security wall to selectively open or close a passage through said security wall between said passenger seating cabin and said safety buffer zone cabin;
a power actuator connected to said security door to actuate said security door to selectively open or close said security door; and
passenger seats installed in said passenger seating cabin; and
wherein there is no passenger seat and no restroom and no other passenger service facility in said safety buffer zone cabin; and
wherein said cockpit door is hermetically sealed in a closed position thereof, said security door is hermetically sealed in a closed position thereof, said cockpit wall is airtight, said security wall is airtight, and said safety buffer zone cabin can be hermetically sealed when said cockpit door and said security door are closed, and further comprising a knock-out gas source providing a knockout gas, and a cam nozzle connected to said knock-out gas source and arranged to introduce said knock-out gas into said safety buffer zone cabin. - View Dependent Claims (5, 6, 7, 8)

9. In a passenger transport aircraft having a fuselage, a cockpit in said fuselage, a cabin area in said fuselage adjacent to said cockpit, a cockpit wall separating said cockpit from said cabin area, and a cockpit door arranged in said cockpit wall to selectively open or close a passage through said cockpit wall between said cabin area and said cockpit,
an improvement comprising a security system for monitoring activities and carrying out preventive measures against aggressive activities of persons in said cabin area, said security system comprising: -
plural sensors that are arranged in said cabin area and that are adapted to sense activities or behavior of persons in said cabin area and to provide corresponding sensor signals dependent on and indicative of said activities or behavior;
an information evaluation and monitoring system having at least one information input, at least one alarm signal output, and at least one actuating signal output, wherein said sensors are connected in a signal transmitting manner to said at least one information input of said information evaluation and monitoring system to provide said sensor signals thereto, and wherein said information evaluation and monitoring system is adapted to evaluate said sensor signals so as to evaluate said activities or behavior and to output at least one alarm signal and/or at least one actuating signal responsively thereto at said at least one alarm signal output and/or said at least one actuating signal output respectively;
